Hello, I am new on CODESYS env. I would like to do some Modbus TCP, but I am wondering If using codesys you must use the device "Modbus_TCP_Client" & "Modbus_TCP_Server". I would like to do it without device, only using ST. Is that possible ? I try the example : MODBUS_master_example, but it is not working. If it is possible to dot it without any Device I will show my code. Thx a lot
Your right, much easier with Linux control SL ARM. Everything is working.
No, my vpn is 10.0.0.12. The docker interface is 172.17.0.1.
I do not have error anymore using nic with eth0 value. But my network it still 172.17.0.3 like the first picture.
Maybe I don't know. **Maybe if someone know it can help me. ** I will try Constrol SL runtime in the Host. I will try to but only Nic without IP
I made a mistake it is not end0 but eth0. But I have the same error.
For small project, I would like to use my industrial computer as a PLC + Industrial Computer. Like that I can save the cost of one PLC. That why I am using Codesys on Linux. With the nic it is not working. I already set the IP adress with /etc/network/interfaces. Can it comes from there ? looking to "Control Linux SL" docuemntation it should work with rtu.
